    (or equivalent directory) after installation to enable the

    To enable your system to find the <SPAN

    shell start-up file unless you installed into a location that is
    searched by default:

>    The environment variables <TT
CLASS="ENVAR"
>PGHOST</TT
> and <TT
CLASS="ENVAR"
>PGPORT</TT
>
    specify to client applications the host and port of the database
    server, overriding the compiled-in defaults. If you are going to
    run client applications remotely then it is convenient if every
    user that plans to use the database sets <TT
CLASS="ENVAR"
>PGHOST</TT
>.  This
    is not required, however; the settings can be communicated via command
    line options to most client programs.
